Abstract:This study is the production of human heart rate measuring instrument based on single chip microcomputer. The piezoelectric ceramic patches as sensors, used to receive the signal of the heart rate. These signals need to be treated with amplification system, shaping, filtering and delivery to the MCU, MCU processing data, and then sent to the display circuit and communication circuit. Display circuit displays the heart rate after data processing, communication circuit is used to connected with the computer, the data is transmitted to the computer. The memory circuit is used to store the measurement data and realize the function of memory. The alarm circuit is used to remind doctors pay attention to measurement data beyond the normal range, which provides a reliable basis for doctors to diagnose disease. The system works by the keyboard set.
Keywords microcontroller Heart rate measuring instrument Sensor
